Zantedeschia plant named &#39;captain ventura&#39;

ABSTRACT

A new and distinct  Zantedeschia  cultivar named ‘CAPTAIN VENTURA’ is disclosed, characterized by large flowers, prolific flower production, strong peduncles, and green foliage occasionally spotted with white. The new variety is commercially suitable for indoor plant production.

LATIN NAME OF THE GENUS AND SPECIES

Zantedeschia sprengeri

VARIETY DENOMINATION

‘CAPTAIN VENTURA’

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program. The new variety originated from a cross pollination, made by the inventor in 2002, of a proprietary seed parent identified as ‘44wit’ and a proprietary pollen parent identified as ‘7849’, both Zantedeschia sprengeri.

The new variety was discovered and selected by the inventor, Anthonius Simon Johannes Kapiteijn, a citizen of the Netherlands, in 2004 among a group of seedlings resulting from the crossing. The new cultivar was found in a commercial green house belonging to the inventor in Anna Paulowna, the Netherlands.

Asexual reproduction of the new cultivar ‘CAPTAIN VENTURA’ was first performed by micropropagation at a commercial laboratory in the Netherlands in 2005. Micropropagated plants were subsequently grown out to produce tubers. ‘CAPTAIN VENTURA’ has been reproduced by both micropropagation and tubers and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘CAPTAIN VENTURA’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘CAPTAIN VENTURA.’ These characteristics in combination distinguish ‘CAPTAIN VENTURA’ as a new and distinct Zantedeschia cultivar:

-   1. Large flowers. -   2. Prolific flower production. -   3. Strong peduncles. -   4. Green foliage occasionally spotted with white.

PARENT COMPARISON

Plants of the new cultivar ‘CAPTAIN VENTURA’ are similar to plants of the seed parent variety, ‘44wit’ in most horticultural characteristics, however, plants of the new cultivar produce larger flowers with longer stems.

Plants of the new cultivar ‘CAPTAIN VENTURA’ are similar to plants of the pollen parent variety, ‘7849’ in most horticultural characteristics, however, plants of the new cultivar produce brighter white flowers.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘CAPTAIN VENTURA’ are similar to plants of the unpatented variety, Zantedeschia sprengeri ‘Crystal Blush’ in most horticultural characteristics, however, plants of the new cultivar have larger, broader flowers. Additionally flowers of ‘CAPTAIN VENTURA’ do not turn pink with age as easily as ‘Crystal Blush.’

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color typical plants of ‘CAPTAIN VENTURA’ grown in a greenhouse in the Netherlands. The plants are approximately 2 years old, shown growing in ground beds. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
